Hope this helps
Answer: a(n) = 5 - 3n
the sequence has:
a1 = 2
a2 = -1
a3 = -7
.........
we can see that: a2 - a1 = a3 - a2 = -3
=> the sequence is a arithmetic sequence
=> the distance between the numbers is d = -3
because this sequence is a arithmetic sequence
=> a(n) = a1 + (n - 1)d = 2 + (n - 1).(-3) = 5 - 3n
Step-by-step explanation:
The answer is B x=13sin75/sin50
Answer:
13 units
Step-by-step explanation:
Im doin this in class to so i got you
the equation would be d=(8-(-5))2-(-3-(-2))2
Next solve in the parenthesis 13 power of 2 +-1 power of 2
Then do the powers 169+1
d=170
Then you square 170 which is 13.03840481
That simplifies to 13
yayyyy
